ON THREE DIGENEAN TREMATODES (FAMILY BUCEPHALIDAE) FROM MARINE TELEOST FISHES WITH NEW RECORD FROM THE RED SEA

T^hree bucephalid species (Trematoda: Digenea: Bucephalidae) belonging to different genera were recorded and redescribed for the first time from the Red Sea fishes. These worms include: Prosorhynchoides arcuatus (Linton, 1900) Bray, 1984 from the pyloric caeca and intestine of Variola lout I Myorhynchus pritchardae Durio and Manter, 1968 from the intestine of Epinephelus malabaricus, and BucephaJopsis sirogylurae (Hopkins, 1954) Yamaguti, 1958 from the intestine of Hyporhamphus gambamr. In starved fishes (Kept alive in the aqurium), individuals of P. arcuatus were only found in the pyloric caeca, but in freshly caught fishes, they were found aggregated in the anterior intestine. This backward migration of the worms was briefly discusscd. The thorough redescription of M. pritchardae (the type and the only species in the genus) revealed that Myorhynchus is actually a synonym of the genus Prosorhynchns Odhner, 1905. Therefore, M. pritchardae wt*s renamed as P. pritchardae (Durio and Manter, 1968) as a new combination. Also, the broadened redescription of B. sirogylurae revealed that B. hemirhamphi Fischthal and Nasir, 1974 is actually a synonym of this species.
